Description

Technical Field

[0001] This utility model relates to the field of rotor core assembly technology, specifically a device for detecting the height of motor stator and rotor cores. Background Technology

[0002] Traditional testing methods involve manual point-by-point measurement using vernier calipers or micrometers, which is insufficient for large-scale production. Manual operation is prone to measurement errors, leading to excessive motor vibration after core assembly. Furthermore, another method, using molds, cannot adequately accommodate different measurement dimensions. Therefore, those skilled in the art have provided a device for detecting the height of motor stator and rotor cores to address the problems mentioned in the background section. Utility Model Content

[0003] The purpose of this invention is to provide a device for detecting the height of the stator and rotor cores of an electric motor, so as to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: A device for detecting the height of a motor stator and rotor core includes a base. A fixed frame is fixedly connected to the upper end of the base. An up-and-down adjustment assembly is provided on the fixed frame. A measuring assembly is connected to the fixed frame through the up-and-down adjustment assembly. The measuring assembly includes a return spring, a sliding sleeve, a connecting sleeve, a limit rod, a receiving plate, a connecting block, a lower pressure plate, a platform, and an electronic scale component. A limit rod is fixedly connected to the upper end of the base. A sliding sleeve is slidably connected to the surface of the limit rod. A connecting sleeve is slidably connected to the surface of the sliding sleeve. A receiving plate is slidably connected to the surface of the sliding sleeve through the connecting sleeve. A connecting block is fixedly connected to the lower end of the receiving plate. A lower pressure plate is fixedly connected to the lower end of the connecting block. A platform is fixedly connected to the surface of the sliding sleeve. An electronic scale component is fixedly connected to the platform. A return spring is sleeved on the surface of the limit rod.

[0005] Furthermore, the up-down adjustment assembly includes a limit slide rail, a sliding block, a servo motor, a threaded rod, a bearing, and a support block. The servo motor is fixedly connected to the fixed frame, and the threaded rod is rotatably connected to the output end of the servo motor.

[0006] Furthermore, a support block is fixedly connected to the inner surface of the fixed frame, a bearing is fixedly connected to the support block, and the lower end of the threaded rod is rotatably connected to the bearing.

[0007] Furthermore, a limiting slide rail is fixedly connected to the surface of the fixed frame, and a sliding block is slidably connected to the limiting slide rail.

[0008] Furthermore, one end of the receiving plate is threadedly connected to the threaded rod.

[0009] Furthermore, the lower pressure plate is slidably connected to the sliding sleeve via an alloy lug.

[0010] Furthermore, the upper and lower ends of the reset spring abut against the sliding sleeve and the base, respectively.

[0011] By adopting the above technical solution Compared with the prior art, the beneficial effects of this utility model are: 1. By using the servo motor in the up-down adjustment component to drive the threaded rod to rotate, the measuring component can move up and down quickly.

The electronic scale component in the measuring assembly works in coordination to ensure that the weight of the iron core is known before the measuring assembly is started, so as to effectively intercept products with large defects and effectively save production resources. 3. At the same time, the electronic scale can also be used as a feedback inhibition component of the up-and-down adjustment assembly to control the stable operation of the device; 4. The return spring effectively cushions the pressure of the measuring components, thus ensuring that the product is not damaged during measurement. Attached Figure Description

[0013] To make the technical means, creative features, achieved objectives and effects of this utility model easier to understand, the present utility model is further described below in conjunction with specific embodiments. In the description of this utility model, it should be noted that the terms "upper," "lower," "inner," "outer," "front end," "rear end," "both ends," "one end," and "the other end," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description. For those skilled in the art, the specific meaning of the above terms in this utility model can be understood according to the specific circumstances.

[0014] Please see Figures 1-4 This utility model provides an embodiment of a motor stator and rotor core height detection device, including a base 1, a fixed frame 4 fixedly connected to the upper end of the base 1, an up-and-down adjustment component provided on the fixed frame 4, and a measuring component for measuring height connected to the fixed frame 4 through the up-and-down adjustment component.

[0015] In this embodiment, the up-and-down adjustment assembly includes a limiting slide rail 5, a sliding block 6, a servo motor 9, a threaded rod 15, a bearing 16, and a support block 17. The servo motor 9 is fixedly connected to the fixed frame 4, and the threaded rod 15 is rotatably connected to the output end of the servo motor 9. The support block 17 is fixedly connected to the inner surface of the fixed frame 4, and the bearing 16 is fixedly connected to the support block 17. The lower end of the threaded rod 15 is rotatably connected to the bearing 16. The limiting slide rail 5 is fixedly connected to the surface of the fixed frame 4, and the sliding block 6 is slidably connected to the limiting slide rail 5. The servo motor 9 can drive the threaded rod 15 to rotate, thereby allowing the receiving plate 10 to be adjusted up and down. At this time, the sliding block 6 slides on the surface of the limiting slide rail 5, which can ensure that the receiving plate 10 moves vertically.

[0016] In this embodiment, the measuring assembly includes a reset spring 2, a sliding sleeve 3, a connecting sleeve 7, a limiting rod 8, a receiving plate 10, a connecting block 11, a lower pressure plate 12, a platform 13, and an electronic scale component 14. A limiting rod 8 is fixedly connected to the upper end of the base 1. A sliding sleeve 3 is slidably connected to the surface of the limiting rod 8. A connecting sleeve 7 is slidably connected to the surface of the sliding sleeve 3, and the receiving plate 10 is slidably connected to the sliding sleeve 3 via the connecting sleeve 7. One end of the receiving plate 10 is threadedly connected to a threaded rod 15, and a connecting block 11 is fixedly connected to the lower end of the receiving plate 10. The lower end of the connecting block 11 is fixed... A lower pressure plate 12 is connected and slidably connected to a sliding sleeve 3 via alloy lugs. A platform 13 is fixedly connected to the surface of the sliding sleeve 3, and an electronic scale component 14 is fixedly connected to the platform 13. A return spring 2 is sleeved on the surface of the limiting rod 8, and the upper and lower ends of the return spring 2 abut against the sliding sleeve 3 and the base 1, respectively. A servo motor 9 drives a threaded rod 15 to lower the measuring component. When the lower pressure plate 12 contacts the platform 13, the origin switch is triggered, and the zero position is automatically calibrated. The iron core to be tested is placed on the platform 13, and the electronic scale displays the weight data in real time. If the weight exceeds the standard range, the system automatically alarms and prohibits the start of detection, starts the servo motor 9, and drives the measuring component to lower. When the lower pressure plate 12 contacts the top surface of the iron core, the data of the electronic scale component 14 changes. At this time, the position of the lower pressure plate 12 is recorded and compared with the initial zero position to determine the height of the iron core.

[0017] Servo motor 9 drives threaded rod 15 to lower the measuring component. When the pressure plate 12 contacts the stage 13, the origin switch is triggered to automatically calibrate the zero position. The iron core is placed on the stage 13, and the electronic scale monitors the weight in real time. If the weight exceeds the ±5% threshold, the system prohibits detection and alarms to intercept products with major defects. Servo motor 9 drives the pressure plate 12 to lower. After contacting the top surface of the iron core, it switches to constant force mode. The weight change is fed back by electronic scale component 14 to record the height. The height of the iron core is calculated by combining the zero position data. The reset spring 2 buffers the downward pressing process to protect the iron core from damage.

[0018] By using the servo motor 9 in the up-and-down adjustment assembly to drive the threaded rod 15 to rotate, the measuring assembly can move up and down rapidly. The height of the iron core can then be determined by the feedback of the reaction force during collision and the travel process. The automated operation of the up-and-down adjustment assembly reduces manual intervention, avoids pauses and adjustments during manual operation, makes the testing process smoother, and further improves testing efficiency. The electronic scale component 14 in the measuring assembly assists in the coordinated work, ensuring that the weight of the iron core is initially known before the measuring assembly starts to ensure that it meets the standard range. This can effectively intercept products with large defects and effectively save production resources. At the same time, the electronic scale can also be used as a feedback prohibition component of the up-and-down adjustment assembly to control the stable operation of the device. The return spring 2 can effectively buffer the downward pressure of the measuring assembly, thereby ensuring that the product is not damaged during measurement.

[0019] This specification describes embodiments, but not every embodiment contains only one independent technical solution. This way of describing the specification is only for clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
